ALEXANDER HALECKI, 0F BARNESBORO, PENNSYLVANIA.

PRESSURE-REGULATOR FOR STEAM-BOILERS.

Application filed May 9, 1911.

To all whom 2'25 may concern Be it known that I, ALEXANDER HALnoKI, a subject of the Emperor of Russia, residing at Barnesboro, in the county of Cambria and State of Pennsylvania, have invented a new and useful Pressure-Regulator for Steam- Boilers, of which the following is a specification.

The invention relates to improvements in pressure regulators for steam boilers.

The object of the present invention is to improve the construction of pressure regulators for steam boilers, and to provide a simple and comparatively inexpensive pressure regulator, designed for use in steam heating systems, and equipped with means for automatically controlling a plurality of burners, and capable of being readily adjusted to enable the desired steam pressure to be maintained within the boiler.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a side elevation of a steam pressure regulator, constructed in accordance with this invention. Fig. 3 is a plan view partly in section. Fig. i is an enlarged sectional view on the line 4-4 ofFig. 3. Fig. 5 is a plan view partly in section, showing the regulator applied to a gas burner. Fig. 6 is a vertical sectional view of the same.

Like numerals of reference designate corresponding parts in all the figures of the drawings. I

In the accompanying drawlngs 1n whlch is illustrated the preferred embodiment of the invention, the pressure regulator is shown applied to a steam boiler 1, forming the subject-matter of a companion application, executed of even date herewith. The boiler 1, as set forth in the said application, is heated by a plurality of lamps or heaters 2, provided with wick raising and lowering devices 3. The wick raising and lowering Specification of Letters Patent.

devices for controlling the burners may be of any desired construction, and their shafts or spindles 4 are provided with outer squared ends 5, which fit in sockets 6 of a plurality of operating shafts 7, disposed transversely of the boiler and mounted in suitable bearings 8. The inner ends of the operating shafts may be connected with the burner adjusting devices in any other desired manner, and they are provided at their outer ends with worm wheels 9, meshing with a plurality of worms 10, mounted on a longitudinal 'shaft 11. The longitudinal shaft 11 is j ournaled in suitable bearings 13 at one side of the support, and the said shaft 11 is provided at its front end with a pinion 15, which meshes with a gear wheel 18 of a short counter-shaft 19. The counter-shaft is ournaled in suitable bearings 20 and 21 at the top of the support 16, and it is provided at its front or outer end with a pinion 22, which meshes with a rack 23 of a piston rod 24-. The piston rod 24, which is square, is connected at its inner end with a piston 25, operating within a horizontal cylinder 26, arranged at one end of the boiler 1 and disposed transversely thereof and connected at one end with the same by a pressure pipe 27, extending from the cylinder to the top of the boiler and adapted to admit steam pressure back of the piston 25. The cylinder is supported by suitable standards 28, and it is provided at its outer end with a head 29, having a central squared opening 30 through which the piston operates and which prevents rotary movement of the piston, in order to maintain the teeth 23 of the rack in engagement with the pinion of the counter shaft. The cylinder is provided adjacent to its outer end with vent openings 31 for the escape of air, and it also has adjacent to its outer end steam escape openings 32, which are uncovered by the piston when the latter is at the limit of its outward movement, and which operate as a safety valve to permit the steam to blow off before the pressure within the boiler becomes sufiiciently high to be dangerous.

The head 29 projects beyond the cylinder to form an annular attaching flange or portion 33 to which are secured the inner ends of an annular series of spring coils 34, which are connected at their outer ends to a movable disk or head 35, carried by the piston rod. The inner and outer ends of the springs are det-achably secured to the flange 33 and to the head 35 by eye bolts 36 and 37, piercing the flange and the head 35 and equipped with nuts. Any number of springs of the desired strength may be e1 ployed and by varying the number of springs and the strength thereof, the pressure within the boiler may be varied to suit the conditions of weather. The head 35, which is provided with a central opening to receive the piston rod 24, is adjustably mounted thereon by means of set collars 38, provided with set screws 39 and adapted to permit the head to be adjusted on the piston rod to place the springs under the desired tension. The cylinder is equipped with an oil cup 40 for lubricating the piston 25.

When the pressure within the'boiler increases beyond a predetermined point, the piston is forced outwardly in the cylinder 26, and the rack of the piston rod rotates the pinion of the counter-shaft and motion is communicated through the gearing to the transverse operating shafts, which adjust the burners and reduce the head, and when the steam pressure is correspondingly reduced, the piston moves inwardly and the wicks of the burner are raised to their normal position. The springs are designed to be maintained under a certain tension, so that if the steam pressure should fall below a predetermined degree, the piston will be moved inwardly and will raise the wicks and increase the heat. By this construction, a constant pressure may be maintained within the steam boiler.

In Figs. 5 and 6, the pressure regulator is shown applied to a gas burner etl, connected with a gas pipe 42, which is equipped with a valve 4L3. The valve 43 is provided with a squared stem 44, which is fitted in a socket 45 of a transverse operating shaft 4E6,

similar to those heretofore described. As the valve 43 will control the supply of gas to any number of burners, only one operating shaft 4:6 is necessary. The gas pipe 42- is also provided with a valve a? to enable the flow of gas to be cut off by hand.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
